To all rrhom it may coacerwk.V Beit known that we, CHARLES E. BOLTON,FRANK H. STRIEBY', and MATTHEW RANKIN, of, Cleveland, in the county ofCuyahoga and State of Ohio, -have invented certain new and usefulImprovements in B0X or Package Fillf ers; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such' as'will enable others skilled in the art to which it pertains tomake and use it, reference being had to the accompanying drawings, whichform part of this speciiica tion.

Our invention relates to a new and useful .improvement in box andpackage fillers, and is designed as an improvement upon the de -vicepatented by Bolton land Streby, February 18, 1879, No. 212.349.'

Uur-invention coi1s1*sts,`iirst, iii mechanism whereby thematerial iscaused to feed uniformly from the hopper, consisting of mechanism foragitating the hopper; second y, in rounding the loweriiiside edge of thehopper, to prevent the feeding blades or valves from clogging; also, inmeans for adjusting thedistance throughy which the hop, @pis agitated.

In the drawings, Figure l is a 4plan View. Fig. 2 isa 'lon gitudinalcentral section through the hopper, illustrating the rounding of itsinner lower corner. Fig. 3 is a separate view in section and elevation,illustrating the man- 11er of agitating and adjusting the distancethrough which the hopper is agitated.

' lcretofore, in the employment of the inacliin-e above 'mentioned, ithas proven exceedvingly difficult to make the' hopper'feed uni- "formlyinto the different boxes vor packages, and this` has beeirtruenotwithstanding the adjustable plate employed in that apparatus. In thesaid drawings, A is a suitable frame. Bis the drive-shaft. C is thehopper. D is the lever by which the yupper valves, D', arev opened inorderto ll the measures below. -E is the lever b'y which the. lowervalves, E', are opened in order to discharge from the said measures intothe packages` Heretofore thehopper has not been agitated l but Weconnect thehopper with the driving mechanism in any suitable manner soasQto agitate the said hopper, in order that the material within thehopper' shall feed uniformly through the upper valves into the measures.

This maybe accomplished iiiaiiy desired manner, the means shown iiitlicdrawings heing practicable, in which Cl are projections extendingdown from the hopper and bearing upon ratchetcams C'l on the shaft B, sothat with every revolution Iof the shaft the hopper l is agitated oneorinoretimes, depending upon the number of ratchets on lthe cani C?.Similar cams located between the sides of the frame may serve to agitatothe tray which contains the Vboxes or packages, in order to settle thematerial in the latter.

In order that the degree of agitation of the hopper maybe regulated, Weprovide any suitable means for this purpese,'and\have foundA thefollowing to be very efficacious: F is a stationary inclined bearingforsurface, upon which rests a wedge, G, Which i/vedge may be adjusted outor in by a screw, G. `The upper portion of this Wedge bears against aportion of the hopper-frame, so that by adjusting .the Wedge in oroutthe hopper maybe brought nearer to or farther from the cams C2, andthereby causethe agitation to be correspondingly altered.

H is a fillet, occupying the lower inside edge of the hopper upon thatside toward which the valve D' closes after the measures have beenfilled. If such a llet is not employed, the valve in closing willcompress or cake a portion of the material between its edge and themethod here shown for agitating the hopper,

nor to the particular means for adjusting the throw of the hopperii1agitatingit,fo various appliances might be employed yvhi wouldaccomplish thesame object. f

.2 erases Heretofore we have found that when apparatus for agitating thetray beneath the hopper has been located at the ends of the tray, thematerial at the center was not properly settled. We have therefore foundit advisable to employ agitatiug apparatus which will operate upon thetrayat different points between the ends, as well as at the ends. This,as before explained, may be by any suitable means. [n ,the drawings camsG3 are employed for the purpose, though, if desired, a ,single cam maybe made to extendfrom one end of the tray to the other, so as to bearupon it' throughout.

l. In a box or package filler, the combination, with a hopper, ofmechanism, substair tially as described, adapted to agitate said hopperwhile the material is being fed` into Athe measures, substantially asset forth.

2. The hoppcrC, in combination with a cam, U2, whereby the hopper isagitated, substantially as andfor the purposes described.

3. The combination, with the hopper and a cam for agitating the same,ot' an adjustable wedge, lr, whereby the distance through which thehopper is agitated is regulated, substantially as and for the purposesdescribed.

et. The combination, with the hopper and agitating-cam, of mechanism forregulat' the thro w" of the hopper as it is agitated, sncstantially asand for the purposes described.

5. The combination, with the hopper and. valve D', of the fillet H,whereby the packirof the material in front of the valve vented,substantially as and for the purp., f described. I 6. The combination,withv the hopper, stationary bearing F, wedge G, and adjustin screw G',substantially as and for the par poses described.

7. In a box or package ller, the tion, with the tray for holding thepackages to be filled, of agitating a' adapted to operate against thetray a whole length, or at the ends and at inten.l` diate points,substantially as and for the pur .poses described.

In testimony whereof` We have signed eur names to this specification inthe presence ef two subscribing Witnesses.
